Framing Strategies for Robustness in Steel Buildings
This paper presents a summary of an ongoing research studying framing strategies to increase the robustness in steel buildings by using stiff stories that can limit deformations capable of causing fracture and other undesirable limit states in cases of column loss. A catalog of buildings that incorporate stiff-story concepts is first presented. Buildings catalogued used the stiff-story concepts for architectural reasons or land space limitations rather than for increased robustness. Two buildings adapted from this catalog were further analyzed for column loss; the analysis and results for one building are presented. Linear static alternate path analyses according to the UFC 4-023-03 guidelines were performed and are presented. Nonlinear static analyses are in progress. Results from the linear static alternate path analysis showed that only five members were overstressed. However, only a few modifications were required to satisfy the UFC guidelines, proving the potential of the stiff-story solutions to resist column loss.
